Conditions at Los Patos in May
May: First Taste of Summer Smallness
May marks the beginning of the low season at Los Patos. The average swell height drops to 4-5ft (1.4m) and the average period slides to 9.9s, shifting the character from powerful groundswell to a more disorganized mix of swell and windswell. There is still plenty of north energy, with NNE at 32.3%, NNW at 34.2%, N at 19.3% and NW at 10.5%, but the shorter period means it demands more cooperation from the tide and wind to line up.
Wind is the real limiting factor: ideal wind is just 12%, the lowest of the year. NE wind takes a commanding 29.7% share, NNE adds 22.0%, and ENE contributes 11.7%, so cross-shore trade winds become the daily norm. Most waves fall in the 3-5ft (1-1.5m) fun-sized range, with occasional 5-6.5ft (1.5-2m) sets from NNE/NNW. Air temperature averages 19.0°C, water temperature is 20.1°C, and precipitation is minimal at 0.25 mm/day. Spring suits and longboards will get the most work.
